What are the features of the fit between the inner ring of the rolling bearing and the shaft, the outer ring and the bearing housing? How do they fit in the assembly drawing?
The simple point that is the bearing surface as the base, so the inner hole is a hole based system of interference fit, but for the bearing convenient disassembly, the amount of interference can not be too large such as H7/k6, the outer ring shaft is fit, such as h7/M6
The inner ring of the rolling bearing is matched with the shaft tightly, the outer diameter of the shaft is larger than the inner ring of the bearing, and the outer ring of the 0.01-0.02MM is matched with the bearing chamber to be matched with the zero.
The inner ring of the rolling bearing is matched with the shaft by the base hole, and the assembly is only marked with the tolerance band of the basic dimension and the axis in the assembly drawing;The outer ring of the rolling bearing is matched with the base of the bearing base by the base shaft, and the mating is only marked with the tolerance of the basic size and the hole in the assembly drawing
